Open Source mindset

Linux came on the Operating Systems scene during last decade of 20th century, how many new operating systems have come after ?

RISCV instruction set (ISA) came around 2015 as 5th Generation of RISC ISA from University of California Berkley, ( 4th Generation went into MIPS architecture ), this would be the last ISA we will use for CPU designs for foreseabale future.

Zephyr Real-Time Operating System (RTOS) came around 2015-2016, this has been gaining on all Microcontroller software and I think this will be the RTOS we will have for a good while into future.

First GNU Compiler collection and then LLVM project came and no one writes new compilers anymore.

What is common in all of the above ?

They all are open source software. If done well, OpenSource methodology builds a solid foundation on which we can stand on and build new things.

Think open do open !!
